Iptables v1.4.4 + kernel 2.6.31 mangle marking changed?

[Ralph de Boom <lkml@deboom.biz>]

Hi there,

Excuse me if this email might go wrong, it's my first message to a 
mailing list.

But here's my problem: (And I hope you guys could shed light for me...)

I originally ran Debian Lenny on kernel 2.6.18.
Since today I reinstalled it to Ubuntu Server 9.10 with kernel  2.6.31.

Now I used to do this in lenny:

iptables -t mangle -A PREROUTING -s 192.168.1.0/24 -d 81.4.97.0/24 -j 
MARK --set-mark 0x1

This would cause relevant packets to be marked 0x1, which in return I 
had a 'ip rule':

my rules look like this:

ip rule show
0:      from all lookup local
32760:  from all fwmark 0x2 lookup upc
32761:  from all fwmark 0x1 lookup xs4all
32762:  from 192.168.1.XX lookup xs4all
32763:  from 192.168.1.XX lookup upc
32764:  from 24.132.104.XXX lookup upc
32765:  from 192.168.2.XX lookup xs4all
32766:  from all lookup main
32767:  from all lookup default

And my 'xs4all' table looks like:

ip route show table xs4all
192.168.2.0/24 dev eth0  proto kernel  scope link  src 192.168.2.XX
default via 192.168.2.X dev eth0


I know the rule matches packets i make:

 iptables -t mangle -v -L
Chain PREROUTING (policy ACCEPT 3111K packets, 1861M bytes)
 pkts bytes target     prot opt in     out     source               
destination
   16  1100 MARK       all  --  any    any     192.168.1.0/24       
ip-space.by.proserve.nl/24 MARK xset 0x1/0xffffffff

But somehow the connection is never relayed over the xs4all table...

The changes I've noticed compared to lenny:

iptables now likes to mark my --set-mark 0x1 as a --set-xmark 
0x1/0xffffffff
whereas in lenny it would stay a --set-mark 0x1

Would be very pleased if someone could help me in this matter.

Greetings,
